Briey, the invention utilizes a chuck for gripping the moil and a holderfor holding the ware in axial alignment with a burner. At the start ofthe operation, the glassware with moil attached is placed in the holder.The burner then moves vertically with its annular :llame against thewalls of the glass serving as a means to polish the glass. The continuedvertical movement of the unit causes the ware holder to be picked up andmoved vertically along with the burner so as to bring the moil intoengagement with the moil gripping chuck. At the same time, suction isapplied to the base of the ware by the holder. The jaws of the chuckgrip the moil and together with the holder cause the relative rotationVbetween the glassware and xed annular flame.

A cam control mechanism holds the burner and the ware holder units at axed elevation for a principal glass wall softening period andiinmediately thereafter, the ware is lowered away from the moil apredetermined distance/'and the softened wall of the glass is stretched.The severance of the moil of the ware is completed by continuedapplication of the flame at the The ware and burner then begin todescend during which time the application of ame at the severed edgewith rotation of the .ware results in the formation of the suction onthe base thereof is released and then as soon as the burner con-ipleteslits descent or at any other portion of the travel of the burner as maybe desired, the oxygen 'supply of the Vvfiance is stopped and thetemperature of thefflafn dropped. This results in the iinished 'articlebeing elevated above the burnerwiththef-suctioni.s

removed ready to be replaced by another piece of glassware for arepeated cycle of operation." l

Referring invdetail to the drawing, the apparai,

tus consists of a `moil Vgripping chuck unit 2, a burnerv 4,y and aware'holder unit 6, all of which 'are'in axial alignment whenpositioned-for severance-'of the moil from the ware. However, for thedisposal of the moll, the chuck unit swings out ofthe axial alignment asshown in Figure 3.

The burner' 4, which is of conventional type, is

Vsupplied through injector 8 which connects through globe valve l0 toagas'line I2 and through globe valve i4 to an oxygen supply line i6.

The burner 4 is supported upon bracket iB which is mounted uponthe-slide20, which, in turn, is

carried by the rectangular slideway 22 for vertical r'eciprocati'on. Asecond bracket 24 is also mounted upon 'theslide 2U,`this latter bracket24 serving 'to raise and lower the ware holder as will be described morefully hereinafter.

The lbrackets' |78V and 24 constitute angular extensions of a' platemember 28 which has slots 28 through which bolts 3l) extend forfastening the@ plate 26 to the rear portion 32 of the slide 2B.

At the base of the slide 20, there is a. lug 34 whichcarries-anfadju'stment screw 35. The ad- 1 ust'ment screw 3-Sfperm`itsfthe -plate 2B and the integral brackets -l'S-and 24 to be raised orlowered by sliding the plate 26 entire-bolts 3S', so as to adjust theposition of the burner and holder relative to the moil gripping lchuckduring the severin'g operation andvthusfpermit the accommodation ofglass articles of different size.

The slide lis provided with extensions 38 and which carryl rollers 4.These rollers 4B rest upon levers `42 which are pivoted at the fulcrumend 44 on the brace' 4d by means of pin 48. Between the free end 4|'`and the fulcr'um end 44 of the lever 42, there is positioned by meansof a pin 50, and between the two separate levers, a roller 52. Thisroller 52 rides upon a cam 54 and thus, serves to raise and lower theslide 2t Vthrough movement of the lever 42 by the cam 54.

The ware holder 6 consists of ring centered bottom plate 55.V havingperforations 58 about which is placed a ring of asbestos 60. TheV plate56 is attached by vapor-tight connection to the tubular shaft 62. Thisshaft passes through an opening 64 in the bracket 24 and slides in abearing 65, carried by the bracket 24. The upper portion of the shaft 62is supplied with threads 68 which serve to position the yadjustment nutlll.V Adjustment of the distance between the holder 6 and the burner '4,when the burner and holder are both in their uppermost position, so asto accommodate glass articleszofivariouslsizes is accomplished byrunning Athe hut 'l0 up or down dthe threads 58 the required distance toproperly position the burner 4 relative to the ware.

The lower part of the shaft 62 passes through a bearing 'l2 which isattached to the base 'I4 of the apparatus. At the lower end of thebearing T2 there is a gear 'i6 which is keyed to the shaft 62 and servesto rotate the lshaft 62 and the vholderf. The key way T8 in the shaft B2extends" throughout its length so'that the shaft may slide lengthwise inthe bearing 'l2 and the gear 1E while being rotated.

Y l The gear 15 is held in place against the bottom of the bearing 'l2by plate 8|)y which is positioned 'upon thev base 'i4 `by the spacers82. The plate Sii `'alsofsurlip'orts idler lgears 84 and 86, as well asthe 'ame'quality control unit 88.

Atlthe lower-:end of the shaft $2 there is a suction control valve QQ.This valve 5l), the details 'of 'which are shown in Figure 6, consistsof a chamber 92 having opposed seating surfaces 94 and 96 and-'a hole-98leading into the chamber. The shaft 62- extends into thechamber 92through the hole 98 and there'is provided on the shft 62 within thechamber an annular collar lill). This collar has seating surfaces H32and 104 which match'withthe seating surfaces 84 and 96 respectively ofthe chamber 92. The lower edge of the annular collar lllil is provided`with vent ports The chamber 92 is formed in an extension |08 that isconnected by means of threads IIB upon a tubular shaft H2 which isaxially aligned with the shaft 52. lThe shaft H2 is, in turn, slidablycarriedin a bushing .H4 which is held by means of bracket HB extendingfrom a portion of the base 14. Theopposite end of the bracket H6 isprovided with slots l IlY which permit the bracket to be adjusted todifferent vertical heights. The lower end of the shaft H2 is connectedthrough elbow H3 to a flexible tube |20, which, in turn, connects to thevacuum connection 122 upon the pump |24. l f

v'The operationofthe-holder 6, shaft 62, suction control means Siland-associated parts may be briey described as follows: As seen inFigure; l, atthe-beginning of an operation, the slide 20 will belowered-by means of. the lever 42 to such an extent that the bracket 24and Ibearing G6 are disengaged from'the adjustment nut lil and theburner 4 is near to the holder 6 which is held in an elevated positionfrom the bracket 24, because the annular coll-ar l on thershaft 62'restsupon the seatingl surface which, Vin turn, rests upon the bracket l lt.-As the slide 2E! is raised by the lever 42 through operation of theA cam54, the burner 4 and bracket 24 will correspondingly be raised and thehot annular flame will travel up vthe side of the ware 428. When theslide 20 had risen suiciently sov that the upper surface of the bearing66 on the bracket 24 contacts the adjustment nut 10, the holder 5 -andthe attached shaft 52 will be raised simultaneously with the slide 28and the burner 4, so that throughout the remainder ofthe upward ascentof the slide the relative position yof, the lburner 4, holder 6 and ware{28 will remain the same. Y Y

As soon as4 the shaft 62 is raised, the annular collar |00 will beseparated from the seat 96 and then a short distance further of travelwill cause "the seat |32 to contact seat 94'. As soon as this Icontactof seats 94 and l02 results, the bleeding of air from theatmospherethrough the hole 98 into the chamber 92Y and through the radial portsH16 into the tubular 'shaft H2 will be stopped and "a""suctio'n on the'ba-secr the ware 128 will result nected and the suction will bereleased by the bleeding of air through hole 98 as described above.Further descent of the slide will cause the collar |00 to seat uponsurface 66 and prevent Vfurther descent of the holder 6, so that theburner 4 will then travel down the sides of the ware until the furtherdescent o-f the slide 20 is stopped by the cam 54. Throughout thisentire operation, the shaft 62 and, in turn, holder 6 and Ware |28 arerotated by means of gear 16 and associated gears.

The moil gripping chuck unit 2 consists of a base member which isprovided with tubular extensions |32 and |34. The extension |32 carriesa housing |36 to which the chuck jaws |38 are attached by means of pins|40. The ends |42 of the chuck jaws |38 engage a rod clutch |44. The rodclutch extends through the jaw spindle |46 which rides in bearings |48and |56. The upper end of the jaw spindle |46 is keyed to a gear |52which is driven through idler gears |54 and the gears |56 and |58.

The upper end of the jaw spindle |46 is recessed to receive springY |60which forces against retaining bearing |62 and serves to actuate the rodclutch |44 and chuck jaws |38.

A lever |64 having a forked end |66 is pivoted on pin |10 which issupported by bracket |12 attached to the base |38. The forked end |66 ofthe lever rests upon the bearing |62 of the rod clutch |44, while thefree end of the lever is provided with a roller |14. Y The tubularextension |34 of the base |30 carries a tubular shaft |16. A solid shaft|18 rides within the tubular shaft |16 on the bearings |80 and |82,while the tubular shaft |16 itself rides upon the bearing |64. Thus, itwill be seen that the entire chuck unit 2 is indirectly supported uponthe bearing |84 through the tubular shaft |16 and is free to rotate withthis shaft. However, free rotation of the unit 2 is prevented by meansof the spring |86 which is fastened at one end to the brace 46 by meansof stud |88 and at the other end to the stud |90 which extends from thetubular shaft |16.

The ware holder 6 and the chuck jaws |38 are rotated at the same rate ofspeed indirectly through the shaft |18. Thus, ware holder 6 1s driven bygear 16 which, in turn, is driven by idle gears 84 and 36 and gears |92and |64, the latter gear being fastened directly to the shaft |18.Likewise, chuck jaws |38 are driven through spindle |46 which is keyedto gear |52 driven by idlers |54 and gears |56 and |58, the latter gearbeing attached directly to the shaft |18.

The shaft |18 rides in bearings |86 and |82 which are supported by thetubular shaft |16 and bearing |86 which is supported upon the base 14.The tubular shaft |16 is also supported by the arm support |98. Upon thebearing |96 rests a roller bearing 266 which supports a tubular section'202. On top of the tubular section 202 there is a spiral gear 204 keyedto the shaft |18 and supporting the bearing |84 which in turn supportstubular shaft |16.

Rotation of the drive shaft |18 is accomplished through spiral gear 206which meshes with spiral gear 204 fastened upon the shaft. In turn, gear206 is attached on the output shaft 208 of the transmission 2|0, whichis driven by motor 2|2 through pulley 2 I4, belt 2 I6 and pulley 2 |8,which is attached to the input shaft of the transmission 220. Thearrangements of these pulleys and motor can best be seen in vFigure 2,whereas the arrangement of transmission and gears for the driveshaft canbest be seen in Figure '7. At the opposite end of shaft 220 there isattached pump i 24 which furnishes the vacuum for provision of suctionas described above.

Figures 7 and 9 further shoW the arrangement of the cam 54 and gearshafts associated with the transmission 2|0. Thus, the cam 54 which isattached to shaft 208 consists of a plate 222 fastened to a bushing 224which is keyed to the shaft 208. The plate 222 is provided with a seriesof holes 226 through which bolts 228 may be extended for fasteningadjustment patches 230 to the plate 222. These adjustment patches 230have over-size holes 232 for receiving the bolts '228, so that thelpatches may be adjusted as to position relative to the plate 222 withthe result that a variation in the contour in the cam 54 may be obtainedin order to vary the different steps in the cycle of operation of thisinvention, as will be more fully described hereinafter in relation toFigure 10.

As indicated above, the cam 54 controls the levers 42 and the roller 52which rides upon the cam 54 and is carried between the levers by thelpin 50. In addition, the cam 54 controls the action of the flamequality control means 88. This latter control is accomplished by theraising and lowering of the rod 234 by means of the clevis 236 whichextends over the pin 50.

The details of the flame quality control unit 88 are shown in Figure 8.Thus, at the end of the rod 234, there is threaded a valve plug 238provided with radial holes 240 and 242 and longitudinal hole 246. Theplug 238 rides in fiuidtight bearings 248 and 250 which are contained inthe chamber 252 of the valve housing 254. The' housing 254 which isattached by means of bolts 256 to the base 14 alsol carries bearing 258through which the plug 238 moves. A second chamber 260 is superposedabove the chamber 252 and separated therefrom by means of the bearing250. An inlet tube 262 which is connected by flexible elbow 264 tooxygen supply line 266 enters the chamber 252. The chamber 260 isprovided with oxygen outlet line 268 to which is attached the flexibleoxygen tube |6. The control means 88 is completed by means of an oilshield 218 which is retained between the end of the rod 234 and the endof the plug 246. This shield 210 performs the dual purpose of limitingthe descent of the plug 38 and also prevents oil or othervcombustiblematter from flowing past the bearing 258 into the chambers 252 and 266.

As can be seen by comparison of Figure 5 and Figure 8 when the plug '238is raised through the action of the cam 54 so that hole 242 is abovebearing 250, oxygen will flow from line 266 through control means 88 andline i6 into the burner 4. On the other hand, when the plug is loweredby the action of the cam 54 so that hole 242 is below the bearing 250,the supply of oxygen to line |6 will be cut off. Adjustment can be madeby the clevis 236 so that the oxygen supply to the burner 4 will be cutoff by unit 88 during any desired portion of ascent and descent of theburner during the steps in the cycle of operation.

piece of glassware.

`Returning for consideration ofthe chuck unit 2, it will be seen thatthe gear |58 carries two cams 212 fand 214 which are located on oppositesides of the gear |58 vfrom one another. Cam 212 is positioned upon thegear |58 so as to intermittently engage roller |14 on lever |64 as thegear rotates and to thus actuate the jaws |38 of the chuck, so asV togrip or release the moil.

The cam 214 is responsible for swinging chuck unit 2 for disposal of themoil. Thus,`the cam 214 is located so vas to intermittently engageroller 216 which is located upon semi-circular lever 218. This lever 218is fulcrumed on rectangular `post 28B attached to arm |98. The oppositeend of the lever 218 is provided with slot 282 which slidably engagespin 284 carried by the base |35.

In operation, the gear |58 rotates and carries with it cam 214. At theproper portion of the cycle of operation the roller 216 contacts the cam214 and in so doing, forces the movable end or the lever 218 against thepin 284, thus causing the base |30 to swing as indicated in Figures 3and 4, for the disposal of the moil. rotation of the gear |58 carriesthe roller 216 beyond the peak of the cam 214 and permits the base |30to be drawn back by the action of the spring |86 into position forreceival of another The extent of back swing of the base |30 is governedby stop plate 286, the position of which can be adjusted -by means ofset screw 288 threaded through post 286.

The cam 212 is so positioned relative to the cam 214 so that when theunit 2 has been swung to the side, as shown in Figure 3, the roller |14will engage cam 212 causing the jaws |36 to open and drop the severedmoil 290 down the pipe 292 to a cullet receiver (not shown) The entirechuck unit 2 is provided with a removable cover 294 which is held on theunit by brace 296.

The various steps in the cycle of operation can be explained withreference to Figure l of the drawing. This iigure shows the varioussteps of operation in relationship to the portion of the control cam 54to which they relate. Thus, the cycle of operation comprises a. loadingand unloading step A, a nre polishing step B, a wall softening step C, astretching step D, a severing step E and a beading step F and apolishing and .annealing step G. AS explained above, the relative periodof time during which each of these ,steps is in progress may be variedby means of adjustment of the patches 238 upon hte plate 222.

The operation of the apparatus during the entire cycle may becomprehended by reference to Figure l0 and Figure l.

At the beginning of the operation, i. e., the loading step, the roller52 rides upon the portion A of the cam so that the holder 6 and slideare in the position shown in solid in Figure l. The ware with moilattached is positioned in the holder 6. As the cam 54 revolves, theroller contacts the nre polishing or B portion of the cam so that theslide 29 is raised uniformly with the result that the burner 4 travelsupwardly relative to the ware, impinging an annular flame upon the sidesof the ware, since during this step of operation the holder 6 and ware|28 do not move vertically, but merely rotate. Within this period oftime the bracket 24 has been raised sufiiciently so that the bearing 86has contacted the adjustment nut 16 and the shaft 62 together withholder 6 and ware |28 has been raised along with the burner 4. At thesame time, atmospheric Further bleeding of the suction valve 9i) hasbeen stopped in the fashion described above so 'that the vware is firmlyheld in the holder 6 by means of the applied suction through theperforations 58 'in the plate 56. During the same period of time, thechuck unit 2 has been swung into the .position shown vin dotted sectionin Figure l and the jaws |38 have been clamped over the moil.Y

As the cam continues further rotation, the roller 52 contacts the wallsoftening or C Vportion of the cam. During this period, the glass isrotated within the annular iame without vertical movement, so that theglass at the junction of the moil and ware becomes soft.

Further rotation of the cam brings into play the stretching portion D,with the result that the slide 20, burner 4 and holder 6, together withthe ware |28, are drawn down a short distance away from the moil, whichis retained against vertical movement by the jaws |38. rIhere after, thesevering portion E of the cam operates to cause the flame to completelyburn through the stretched section of the glass. Then the beadingsection Foi the cam operates so that the burner proceeds downwardly withthe ware forming a bead upon the severed edge of the ware. Finally, thepolishing and annealing section G causes further lowering of the slideso that the bearing 66 disengages from the adjustment nut 10 and theburner proceeds dow-n the ware to the unloading position, as shown insolid section in Figure l. At the same time, the position of the plug238 in the control unit 38 has been adjusted through the action of cam54 and rod 234 so that the oxygen supply to the burner has beendiscontinued. The completely severed, polished and annealed ware is thenremoved from the holder, from which the suction has been by this timediscontinued, and a new piece of glassware inserted for a repetition ofthe nishing operation.
